Hi
When I open my files in cfx-pre or post, for each click I 've got this warning" unknown quantity type:relative molecular mass" which is annoying.I have laminar flow with no heat transfer. If I open my file in another computer there is not any warning so probably something wrong in my computer or any setting. any idea?

Thanks

I encountered this problem when I upgraded to v12 from v11 on Windows XP64.

I fixed the problem by closing all Ansys applications and deleting the file 'CFXPreferences.ccl' located in \documents and settings\<user>\.cfx

The file was automatically recreated the next time I loaded CFX.

Hope that helps.

Thanks LKF, I did the same but still no change. Do you have any idea?

If that does not work then exit CFX and delete the whole \documents and settings\<user>\.cfx directory. When you restart CFX you will loose all your defaults and settings but hopefully the error message will go away.
